Choose the option to recover lost or formatted files. This process may vary slightly depending on the software used, but typically involves starting a scan of the selected drive.

7. Scan for Recoverable Files
Allow the program to scan the flash drive. This may take some time depending on the size of the drive and the amount of data.

If data recovery is unsuccessful and only the program needs to be reset, you might need to format the drive again. Ensure any recoverable files are saved before formatting.

10. Reinstall or Restore the Factory Program
For software specific to CooDisk, you may need to contact support or visit the official website to obtain the factory format program again. Alternatively, consider documentation that came with the device for reinstalling the software.
